Abstract

1. Method for the simultaneous transmission of communications, which emanate from an exchange, over several common frequency transmitters, characterized thereby, that the communications are stored or delayed in the common frequency transmitters for a waiting time until the longest possible transit time of the communications from the exchange to the common frequency transmitters has elapsed and that the communications are then transmitted synchronously by the common frequency transmitters on a not necessarily periodic timing signal.
